Not defending Amazon's behavior but the standard for government intervention in antitrust cases has for decades been how the anticompetitive behavior affects consumers, NOT other businesses/sellers.

And it's pretty clear that Amazon has led to much lower prices and a consumer surplus compared to alternatives in the market.

And for all the shit AMZN gets on HN and over social media, broadly it is still one of the most widely respected and popular companies in the US across a broad spectrum of consumers.

You can argue whether that's overall good or bad, but I'm talking about the law as it is and has been enforced vs. what people WISH the law said.
